AKT. 20. ICHNEUMON-FLIES OF TRIBE PANISCINI CUSHMAN. 25 



Propodeum more distinctly rounded or with distinct apophyses; first tergite 

 less than five times as long as wide at apex 25. 



25. Spiracles of first tergite not far before middle; second tergite not much longer 



than wide and but little more than half as long as first- texanus Ashmead. 



Spiracles of first tergite far before middle; second tergite much longer than wide 

 and distinctly more than half as long as first - 26. 



26. Ocelli not nearly contiguous with the eyes (closer in male than in female); 



apophyses weak; small, 10 mm. or less - geminatus (Say). 



Ocelli practically contiguous with the eyes; apophyses strong; large. 



geminatus, var. sayi, new variety. 



PANISCUS PULCHEU, new species. 



Very distinct in the entire lack of sciitellar carinae and the highly 

 contrasting color pattern of the thorax. 



Female. — Length 15 mm.; antennae 15 mm. 



Polished throughout and practically without sculpture; temples buc- 

 cate but much narrower than eyes; occipital carina very weak; face 

 slightly wider than long, the sides slightly convergent below; frons 

 as wide as narrowest part of face; eyes shallowly emarginate; clypeus 

 strongly transverse, broadly and ratlier deeply emarginately trun- 

 cate and transversely elevated; ocelli narrowly separated from eyes, 

 postocellar line nearly as long as ocellar diameter; antennae slender, 

 first flagellar joint much shorter than next two combined, middle 

 joints nearly twice as long as thick. Pronotum slightly roughened 

 in lateral groove; notauli short but deep; scutellum entirely with- 

 out carinae; mesopleurum with a strong Y-shaped groove with its 

 base near the posterior margin; prepectal carina strong and termi- 

 nating abruptly at the lower branch of the groove; propodeum 

 inconspicuously transversely striate, apical carina strong but not 

 prominent laterally, weakly indicated medially; areolet placed 

 nearly longitudinally, the lower side nearly continuous with rest of 

 cubitus, second intercubitus broken ; recurrent nearly straight below 

 middle, incurved abo^e, interstitial, lower bulla well below middle; 

 nervulus postf ureal by more than half its length, perpendicular or 

 nearly; postnervulus broken at its upper third; nervellus broken 

 above its upper fourth; hind femur slender, two-thirds as long as 

 tibia; tibia nearly as long as tarsus; tarsi very slender, apical joint 

 of middle tarsus much shorter than third and only a little larger 

 than fourth, claws small with about ten large teeth and a few small 

 basal ones. Abdomen not strongly compressed; fu'st tergite slightly 

 more than three times as long as wide at apex, spiracle at basal 

 third; second tergite barely longer than wide at apex, slightly less 

 than two-thirds as long as first; sheath two-thirds as long as first 

 tergite. 



Testaceous, this color becoming almost piceous on mesoscutum; 

 head largely yellow, this color including vertex; antennae testaceous; 

 thorax with yellow markings as follows: Margins of mesoscutum and
